Grafting is an artificial form of vegetative propagation in which parts
of two young plants are joined together, first by artificial means and then by
tissue regeneration. Typically, a twig or bud is cut from one plant and joined
to a rooted plant of a related species or variety. The twig or bud is called
the scion, and the plant onto which is it grafted (and that provides the
roots) is called the stock. The scion eventually develops into an entire
shoot system. Grafting often allows horticulturalists to combine the best
features of two different plants into one plant. Sometimes the stock and scion
retain independent characteristics, and sometimes the stock alters the
characteristics of the scion in some desirable way.
